There are several ways that seedless fruits can arise. They are usually an exception to the normal fertilization process. Most seedless fruits have what is termed parthenocarpy, where fruit form without fertilization, but pollination is sometimes required as stimulation.

Which plants are capable of self-pollination?
Plants that are capable of self-pollination include certain types of flowers, such as peas, tomatoes, and beans. These plants have both male and female reproductive organs within the same flower, allowing them to fertilize themselves without the need for external pollinators like bees or wind.
What is the difference between monoecious and diecious?
Monoecious plants have both male and female reproductive organs on the same plant, allowing for self-pollination. Dioecious plants have separate male and female plants, requiring cross-pollination for reproduction.
How is self-pollination and cross-pollination alike?
Both self-pollination and cross-pollination are methods of transferring pollen from the male reproductive organs of a flower to the female reproductive organs. This process is essential for plant reproduction and the production of seeds. The main difference between the two methods is that self-pollination occurs within the same flower or plant, while cross-pollination involves the transfer of pollen between different flowers or plants.
Pollen in plants is most similar to which type of cell in humans?
sperm
Is jasmine unisexual bisexual?

Which plants are capable of self-pollination?
Plants that are capable of self-pollination include certain types of flowers, such as peas, tomatoes, and beans. These plants have both male and female reproductive organs within the same flower, allowing them to fertilize themselves without the need for external pollinators like bees or wind.
Do green algae and plants have similar types of chlorophyll?
Plants and green algae both have the same types of organelles. This is because they both are able to create their own food.
What is the gender of a spinach?
Spinach plants are hermaphroditic, meaning they have both male and female reproductive organs. However, they can also be classified into two types based on their flowering: monoecious spinach plants have both male and female flowers on the same plant, while dioecious spinach plants have separate male and female plants. In cultivation, both types can produce seeds, but the dioecious plants require both genders to ensure pollination and seed production.
Which type of pollination is better self or cross pollination?
Both types of pollination have advantages. Self pollination allows a plant to reproduce even if there are no other plants of the same type nearby. Cross pollination can serve to prevent the extinction of a species due to a lack of genetic variation.
How are fruits and flowers similar?
Fruits and flowers both play a role in the reproduction of plants. Flowers contain reproductive structures that produce pollen and nectar, which attract pollinators. After pollination, flowers develop into fruits, which contain seeds that can grow into new plants.
Do animals depend on plants for shelter pollination seed dispersal or sun light?
yes animals depend on plants for shelter. The plants depend on a variety of animals for pollination, seed dispersal. Sunlight is needed by both plants as well as animals.
How many plants are involved in self pollination?
Self-pollination occurs in a variety of plant species, particularly those with perfect flowers that possess both male and female reproductive organs. It is most common in plants such as peas, beans, and many types of orchids. While exact numbers can vary, it is estimated that around 20-30% of flowering plants are capable of self-pollination. This strategy can be advantageous in stable environments where pollinators are scarce.
Is a squash a staminate or pistillate?
Squash plants are typically monoecious, meaning they have both staminate (male) and pistillate (female) flowers on the same plant. The staminate flowers produce pollen, while the pistillate flowers develop into the fruit after pollination. For optimal fruit production, both types of flowers need to be present and pollination must occur.
How are native and non native plants similar?
they are both plants
What are the 2 forms of pollination in angiosperm plants?
The two forms of pollination in angiosperm plants are self-pollination and cross-pollination. Self-pollination occurs when pollen from the same flower or plant fertilizes its own ovules, while cross-pollination involves the transfer of pollen from the flower of one plant to the ovules of another, promoting genetic diversity. Both methods can effectively lead to fertilization and seed production, but cross-pollination often results in stronger and more adaptable offspring.
What are flowers similar to reproductive organs of animals?
Plants and animals both have male and female reproductive organs. Some orchids put out a scent that resembles the pheromones of the female bee, encouraging pollination of the flowers by (failed) copulation.
Is a form of sexual reproduction?
Yes. Although most plants contain both sexual reproductive systems, pollination takes two plants to occur.
